Well, the shrieks of fear mean a nerve has been struck.
Extant generations of US folks' daily lives, outside a few cities, are built on a history of oily cars + the ability to flee consequences/complications of community life.
Small-town main streets could be 15-minute friendly if small business owners weren't squeezed out by big corporations + globalization.
Cars can be tools of social class enforcement.
Folks fear change.
